Refrigerant Circuit With RESTRICTOR And Reservoir
Arrows point in direction of refrigerant flow.
A-Low pressure side of refrigerant circuit.
B-High pressure side of refrigerant circuit.
| Component | Aggregate State of Refrigerant | Pressure Bar (psi) Positive Pressure | Temperature in Degrees Celsius (Fahrenheit) |
|---|---|---|---|
| -1- A/C compressor B-side | Gas | up to 20 (290) | up to 70 (158) |
| -2- Condenser | From gas to vapor to fluid | up to 20 (290) | up to 70 (158) |
| -3- Restrictor | From fluid to vapor | B-side to 20 (290), A-side greater than 1.5 (21.8) | B-side up to 60 (140), A-side warmer than -4 (25) |
| -4- Evaporator | From vapor to gas | Greater than 1.5 (21.8) | Warmer than -4 (25) |
| -5- Reservoir | Gas | ||
| -6- A/C compressor A-side | Gas |
Pressures on A-side are maintained at approximately 2 bar (29 psi) by "regulating" A/C compressor also at various engine speeds. However, this applies only within the performance range of the A/C compressor; if the performance limits of the A/C compressor are exceeded. Refer to PRESSURES, CHECKING .
NOTE:
In vehicles with A/C Compressor Regulator Valve -N280-, the pressure is modified on the low pressure side by the valve.
